"Would take some stiff competition to beat this design," one person wrote.
"Surely the architect was having a good old laugh with this," another said.
One added: "Looks like someone thought long and hard about that design."
The post was soon taken down and replaced with a different image, with the council addressing the "awkward" situation.
"AWKWARD! We're feeling a little red faced here after posting our skate park design," the council wrote.
"We've changed the photo to one that more accurately reflects what people might expect to see from ground level, as we would hate to set up false expectations — too much pressure for a skate park.
"Thanks to all the clever people in our community for your 'helpful suggestions'."

Tea Tree Gully councillor Olivia Savvas said the council was getting a lot more attention than usual since the design had been posted.
"That being said, all publicity is good publicity and we're hoping to receive plenty of feedback on Bentley Reserve Skate Bowl as a result," she wrote on Facebook
"Share your (genuine) opinion on the Skate Bowl … we're talking about Bentley Reserve Skate Bowl and NOT your husband's!"
Thanks everyone for your huge support of our feedback process for Bentley Reserve skate park. We haven’t been too hard...
